Cataloging for program autoinstall
You can specify whether an autoinstalled program definition is cataloged or not (that is, whether the definition is retained over a warm or emergency start) by using either the PGAICTLG system initialization parameter or the PROGAUTOCTLG option on the CEMT INQUIRE∨SET SYSTEM command.
The values you can specify are:
- ALL
- Autoinstalled program definitions are written to the global catalog at the time of the autoinstall, and following any subsequent modification.
- MODIFY
- Autoinstalled program definitions are cataloged only if the program definition is modified by a SET PROGRAM command subsequent to the autoinstall.
- NONE
- Autoinstalled program definitions are not cataloged. This gives a faster CICS® restart (warm and emergency) compared with the MODIFY or ALL options, because CICS does not reinstall definitions from the global catalog. Definitions are autoinstalled on first reference.
The setting that you specify for cataloging of autoinstalled programs has no effect on programs that are autoinstalled by a task for an application that is deployed on a platform. These programs are never cataloged.
The effects of specifying cataloging for program autoinstall apply mainly to recovery and restart. See Program autoinstall and recovery and restart.
